The most popular method to produce composites for ballistic applications is to use aramid and ultra high molecular weight polyethylene (UHMWPE) fibers as reinforcement materials in different matrices. The composite materials used in this type of application, especially those used as armoring materials for explosions, are subjected to a very high level of energy. In this study, the effect of the reinforcement material type and cross-plied condition of reinforcement were examined using high-level impact tests. The impact tests were performed at low speed but high energy, and thus the behaviour of the composite materials that were exposed to high-level impact energy could be examined. According to the results, the UD aramid composite produced the best results with respect to high-level impact tests. In addition, mass optimisation could be achieved without the loss of the high-level impact energy by preparing a hybrid composite with UD UHMWPE and UD aramid fibers.

Powszechną metodą produkcji kompozytów dla zastosowań balistycznych jest użycie jako wzmocnienia włókien aramidowych oraz włókien polietylenowych o super wysokim ciężarze cząsteczkowym i różnych materiałach matrycy. Materiały kompozytowe stosowane w tego typu rozwiązaniach, specjalnie te stosowane jako materiał wzmacniający w przypadku eksplozji są poddawane testom o bardzo wysokim poziomie energii. W przedstawionej pracy badano efekty zastosowania różnego typu materiałów wzmacniających i ich konfiguracji w strukturze. Badania prowadzono stosując testy udarowe o bardzo wysokiej energii lecz małej prędkości udaru. Dzięki temu można było sprawdzić zachowanie różnych zastosowanych materiałów. W efekcie stwierdzono, że najlepsze wyniki uzyskuje się używając włókna aramidowe. Dodatkowo można było przeprowadzić optymalizacje masy poprzez przygotowanie kompozytów hybrydowych.
